I have seen similar but with the extra code. I was driving my EVO/ Mirage and when squeezing the throttle to climb a grade it backfired and lost power. I could not restart it but since I was running an adapter harness I could plug the factory ECU in and get home. Luckily I had the airflow meter with me.
One other time driving along the engine cut off, this time the plugs were soaking wet with fuel. I changed them and all seemed fine. This was all on the MS1 processor and I do not consider it as stable as the MS2.
